Electroplating

Electroplating is the process of using an electrical direct current to coat an electrically conductive object with a thin layer of metal. EPi offers a variety of high-quality electroplating processes that are ideal for all types of metal finishers. Learn More

Cleaners

All metals need to be cleaned prior to electroplating, blackening, or finishing. Metalworking fluids and carbonaceous smut need to be removed in a soak, spray, electroclean, or ultrasonic cleaning. A properly cleaned part will have excellent adhesion and be brighter, blacker, and smut-free. Learn More

Acid Salts

Dry-powdered and liquid acid salts are specifically formulated for removing rust, scale oxides, stains, and smut from a variety of metal surfaces. Acid salts are also used to activate metal surfaces for further finishing. Learn More

A liquid mixture of surface active agents, detergents, and caustic that floats the oil. Contains over 13% by weight surfactants and detergents. Does not contain silicates. Results in a surface free of residual cleaning solutions. Temperature: 130–190° F. Concentration: 6–15% by volume in water.

A liquid mixture of surface active agents, detergents, and caustic that emulsifies the oil. Contains over 13% by weight surfactants and detergents. Does not contain silicates. Results in a surface free of residual cleaning solutions. Temperature: 130–195° F. Concentration: 6–15% by volume in water.

Most effective when used as a reverse current (anodic) cleaner, although it can be used cathodically. Higher concentration will result in more rapid cleaning and smut removal. Temperature: 180–200° F. Concentration: 8–16 oz/gal of water. Time: 3–6 minutes.

The E-Kleen 125 is recommended as a heavy-duty electrolytic and soak metal cleaner. It removes smut while preventing the redepositing of soils. It should be used without an intervening water rinse prior to an electrolytic solution. Varying temperatures and concentrations should be used on different substrates. Contact EPi for more information.

A heavy-duty liquid detergent that is low-foaming and ideal for cleaning parts in soak cleaning, high-pressure spray washing, and Ransohoff machines.

Effective at low operating temperatures of 100–140° F on all metals without etching aluminum. Contains no chelators and is a low-caustic and non-emulsifiable product. Cleaning time will depend on the type and degree of soil present as well as concentration and temperature. Works well with oil-recovery systems, eliminating dragging in emulsified oils down the finishing line.

Documentation

A heavy-duty liquid mixture of surface active agents, immersion desmutters, detergents, silicate, phosphates, and caustic that will emulsify the soils and oils.

Removes carbon smut on steel and other metals. The E-Kleen 153 creates better adhesion, brighter plated parts, and smut-free parts. Does not contain chelators. Ideal for soak, electro, and ultrasonic cleaning methods. Works well in front of E-Brite 5.0 Cu for zamac alloys for an electrocleaner.

A one-step liquid concentrate blend of acid, solvent, surfactants, and complexers that clean and prep a variety of metal surfaces.

Recommended for use following conventional alkaline soak cleaners to ensure neutralization of residual alkalinity prior to acidic blackening or oxidizing processes. Effective as a surface conditioner and activator prior to blackening. Cleans aluminum well with slow, controlled etching of the aluminum surface.

Contains no chelators or phosphates. Low-foaming and ideal for use in high-pressure spray washing and Ransohoff machines. Low caustic and non-emulsifiable. Do not exceed 150° F. Higher temperatures will decrease the effectiveness of the cleaner. Oil-splitting cleaner works well with oil-recovery systems, preventing emulsified oils from dragging down the finishing line. Also works well in iron phosphate high-pressure spray pre-treatment lines prior to painting.

Effective in removing baked-on carbon, cutting oils, waxes, buffing compounds, and other soils. Works well in black oxide and plating lines. Contains no chelators or phosphates. Low caustic and is a non-emulsifier. Should only be used where an oil separator is in place. Effective at 140° F. However, effectiveness doubles at temperatures above 190° F.
